I have a 1997 36V electric ezgo with very dim headlights and tail lights. The stock wire harness is connected to the main pos and main neg which is putting out 37-39 volts. When I take a reading at the plug sockets I only get 6v. My question is we’re inline is the voltage getting stepped down? There is no visible voltage regulator installed. It does have the three switch key off/on/acc, does the acc only get 12V and could this be bad?
